A More Accurate Field-to-Field Method towards the Wind Retrieval of HY-2B Scatterometer [PDF]

open access: yesRemote Sensing, 2021
In this paper, we present a method for retrieving sea surface wind field (SSWF) from HaiYang-2B (HY-2B) scatterometer data. In contrast to the conventional algorithm, i.e., using a point-to-point (P2P) method based on geophysical model functions (GMF) to

A Modeling Study of the Impact of the Sea Surface Temperature on the Backscattering Coefficient and Wind Field Retrieval [PDF]

open access: yesIEEE Access, 2020
The sea surface temperature (SST) actively impacts the backscattering coefficient measured by scatterometers and the wind retrieval accuracy. However, none of the geophysical model functions (GMFs) currently used in operational wind retrieval considers ...

Mitigation of Sea Ice Contamination in QuikSCAT Wind Retrieval [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2014
Scatterometers provide frequent estimates of near-surface wind vectors over the Earth's oceans. However, in the polar oceans, the presence of sea ice in or near the measurement footprint can adversely affect scatterometer measurements, resulting in inaccurate wind estimates.

Influence of Residual Amplitude and Phase Error for GF-3 Quad-Polarization SAR on Wind Vector Retrieval

open access: yesRemote Sensing, 2022
High-resolution wind vector is important to investigate local winds’ variability over the global ocean. Quad-polarization Synthetic Aperture Radar (SAR) can provide wind vector independently without any external wind direction inputs.

First Assessment of CyGNSS-Incorporated SMAP Sea Surface Salinity Retrieval Over Pan-Tropical Ocean

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In sea surface salinity (SSS) retrieval using L-band passive radiometry, radiometer-independent ocean wind speed is needed as auxiliary data. Wind speed data from scatterometer and weather models are commonly used as auxiliary data in satellite SSS ...

Sea wave modeling with X-band COSMO-SkyMed© SAR-derived wind field forcing and applications in coastal vulnerability assessment [PDF]

open access: yesOcean Science, 2013
In this paper, X-band COSMO-SkyMed© synthetic aperture radar (SAR) wind field data are first used to force coastal wind wave modeling for both sea wave numerical simulation and coastal vulnerability assessment purposes. The SAR-based wind field retrieval
